提高推重比是航空发动机设计追求的最主要目标之一,而高推重比一方面取决于高水平的气动热力学设计,同时也取决于高水平的结构设计技术和方法。本文从结构设计关注点、新颖结构、选材趋势及由此带来的结构设计思维变化等方面,论述了对高推重比的不断追求为结构设计工作所带来的变革和发展。
Increasing the thrust-to-weight ratio is one of the main goals pursued by aeroengine design, which on the one hand depends on the high level of aerodynamic design and on the other hand, the high level of structural design techniques and methods. This article discusses the change and development brought by the continuous pursuit of high thrust-to-weight ratio for structural design from the aspects of structural design focus, novel structure, material selection trend and the resulting structural design thinking changes.
